515201 ÷ 80 
We want to divide 515201 by 80.

Moving on to step 1:
80 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 80

Going ahead to step 2:
If we divide 51 by 80, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 80

Let's proceed to step 3:
515 divided by 80 is 6 with a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 480 from 515 leaves us with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 80

Step 4:
The number 80 fits into 352 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 64.0
If we subtract 320 from 352, we get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 80

Going ahead to step 5:
If we divide 320 by 80, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 644.0
Subtracting 320 from 320 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 80

On to step 6:
When dividing 1 by 80, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 6440.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 80 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 6440.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
80 goes into 100 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 6440.01
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 6440.012
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6440.0125
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6440.0125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6440.0125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6440.0125, with a leftover of 0.0.
